The character will make her first appearance in an episode titled 'The Girl With The Dungeons And Dragons Tattoo' and could be key in helping Dean get to billionaire Dick Roman (James Patrick Stewart), according to TV Guide.

"We were so stoked that she agreed to do the episode because we're all fan girls and boys here," executive producer Sera Gamble said.

"Felicia plays a girl named Charlie who is sort of a lowly tech working in one of Dick Roman's companies. He's an amateur computer hacker and unwittingly gets wrapped up in Sam and Dean's problems. It's a classic story of an everyday girl who does not want to be in a whistleblower position."
